Patented Mar. 1, 1932 UNITED STATES ANDREW e. nrnnnor SEATTLE; WASHINGTON n EGG HEATER Application filed 'October 12,` 1929. Serial No. 399,139.

Thisinvention relates to A novel improvementsin egg beaters `or the like and aims primarily toprovide asanitary separable egg beater, especially designed to be easily and rapidlytaken apart, whereby the beating or Whipping members thereof and related parts arerendered readily accessible for thorough cleaning and proper drying priork tolreassembly of same. t i

Contemplated `A by the present invention is the provision of aseparable egg beater embodying'. alsectinal frame capable of b eing readily dismantled, beaterf members Journalled for rotative movementA within ksaid sectional frame, and means for rotating said beating members, all of which are important features ofthe invention-and are to be correlated in the broad aim of enhancing the eciency of the device for general use- The above, and additional objects which will hereinafter be more specifically treated are attained by such means'as are shownn the accompanyingdrawings, deseribedin the following specification and then more clearly pointed out in t-he claims, which are appended hereto and form part ofthis application.

With reference to the drawings, in which there is illustrated one embodiment of the invention, and throughout the several views of which like charactersof reference designate similar parts: l

Before taking up the detailed kdescription ofthe drawings,a general exposition of the specific purposes, features and;,advantag of the egg beater1 evolvedfby-the presentnvention willbe undertaken. Y y

Heretofore, variousobjeetions to thezegg beaters in generaluse have been notedfprinl cipally among which are: their mode ofconstruction efectually prevents theirV being taken apart forcleaningggreat.v difficulty is experienced vin. properly cleansing and.: drying the same; their. manner of construction effectually precludes repairs thereto, or! the interehanging the several .parts thereof and in many` instances, due to friction-between parts, considerable effort must be exertedto operate same.

It istherefore, the principal aimandfpurpose of this invention to overcome andiohviate these objeetions-,.byk the. provision of a sanitary separable egg beater 2 which is'esf pecially designed and particularly adaptable for rapid. dismantlingI so` that-the several parts thereof are readily accessible fonproper cleansing and vdryingand forquickfreassembly thereafter which iscapable offbeing rapidly` and quickly repaired; which isl constructed to` permit:V ready interchangingor replacing ofparts; andwhiehkis fabrica-ted in a novel manner. to substantially-reduce friction between the several operatingyparts thereof; I Y

Beginningfnow., the more detailed description ofthe inventionby reference-to the drawings, the` numeral, 10 designatesthe upper section of'a sectional egg beater frame, preferably fabricated; from a metallic'bar 8 or strip, the upperend portionofewhlichis bentedgewise at right anglesandgprovided thereat with a handle ll, while its lowersend portion is returnabent flatwiseto form a quadrangular loop l2, with thek terminaliof said portion iXedly l' secured to .the .central portionof the'bar 10, aszby. a rivet 13,- to thereby provide rigidity for theloop 12.'

Rotatively mounted'upon an outwardly projecting shouldered kextension-14; of the rivet-V 13-s a bevel gea-r l5 adaptedto be manually,V rotated by a crank ,ort operating handle 16 riveted or-otherwise rigidlyse.- cured to the periphery. thereof,

Fixedly and medially secured, asbyV a rivet erably fabricated from wire or analogous material of suitable gauge. |I`he upper and lower sections and 20, respectively, of the egg beater frame are adapted to be detachably connected or interlocled, and for this purpose the outer sides of the free upper terminal 'portions of the member 20 areV providedwith notches 21, which normally receive and restrainingly engage the outer ends of the slots 1-9, substantially in the manner illustrated in Figs. 1 and 4.

. ltigidly and medially secured, as by a rivet 22, to the underside of the arcuate lower end of the U-shaped member intransversely disposed-relation thereto is a bar 23, that portion of the member 2O adjacent the point of attachment of the bar 23 thereto being pref-- erably flattened, as shown more clearly in Figs. 6 and 7, in order to furnish a suitable attaching surface for said bar, as will be manifest and apparent.

' Formed within the'bar 23 adjacent the ends thereof are bearings 24, within which are rotatively mounted the lower ends of beater member shafts 25, said shafts having their upper end portions similarly mounted in spaced axially aligned guide bearings 26 formed in the horizontally disposed portions of the quadrangular loop 12. By thus mounting the upper end portions ofthe shafts within the spaced bearings of the quadrangular loop 12, in the manner herein shown and described, such bearings serve andy function to effectually prevent wobbling of the shafts during rotation thereof.

Rigidly secured to the shafts 25, at points thereon below the section 10, are pinions 27, which are normally in mesh, one of said pinions being in normal meshed relation with the bevel gear 15, all as clearly shown in Fig. 2, whereby rotative movement of the bevel gear 15 is imparted to said shafts 25, in opposite directions, as will be evident and apparent. Y Y

The numeral 28 designates beater members, preferably fabricated from relatively thin metallic strips, which are bent or fashioned to form rigid frame-like structures, and are rigidly secured in cross-wise relation upony the lower portion of each of the shafts l25. To increase the agitative effect of the beater members 28, I have found it expedient in practice toprovide the same at intervals throughout their length with thin metallic strips 29, which are iixedly secured at their ends tothe sides of their correlated beater members, the strips of one beater member being disposed in crosswise relation to the strips of its complemental beater member, substantially in the manner shown, at the lower right hand side of Fig. 2.

In Fig. 1 I have illustrated the lower half portion of the legs of the elongated U-shaped member 20, as being outwardly offset or bulged, this for the purpose of providing ample clearance for the rotative beater niembersV 28.

ByV referring to the drawings, it will be evident, that when the device is in use the.

bar23, which is rigidly attached to the U shaped member or lower frame section 20, rests upon the supporting surface, and any downward pressure exerted upon thehandle 11 will be imparted through theupper section 10, its complemental lower section 20, and bar 23 to said supporting surface, so that the shafts 25 are in nowise affected by such downward pressure but have free rotative movement within their bearings at all times.

In the operation of the device,the beater members 28 are placed in the `substance to be treated, whereupon the operator imparts rotation to the bevel gear l5 through the crank handle. 16, to thereby impart reverse rotative movement to in turn impart similar movements to their correlated and interconnected beater `members 28, to thus effect beating or whipping of said substance.

To cleanse the device after use, the operator` exerts an inward pressure upon the upper portion of the U-shaped member 20, to release the notches 21 from engagement with the ends of the Vslots 19, substantially` as shown in Fig. 3, whereupon the upper ends of said member .are withdrawn from said slots, as indicated in dotted lines in said Figure, which latter movement simultaneously effects unseating of the lower ends of the shafts 25 from their bearings 24:, as illustrated in Fig. 7, following which the upper portions of the shafts 25 are withdrawn from their bearings 26. When the devicehas been thus dismantled, the several parts thereof are all readily accessible for proper and thorough cleansing and drying, and upon completion thereof are reassembled by reversing the steps above described.

It is to be here understood, that while the device of the present invention, in its present form, has been described as an egg beater, said device may be employed for other uses and purposes, such as whipping cream, mayonnaise dressing, milk shakes, malted millr drinks, and other substances requiring a like beating or whipping action. It is also tobe understood, that while the device has herein been shown and described as manually operated, the same is readily adaptableand suitable for power operation.

Manifestly, therefore, the device of the the pinions 27', which (iii present invention is extremely simple, com-- pact, durable and economical in construction, is efficient and reliable in use, is conveniently and easily operated, is readily taken apart and reassembled, and will not readily get out of order.

l/Vhile I have herein shown and described the invention with suicient detail to enable those skilled in the art to which it pertains to understand the mode of construction and the principles involved, it is to be understood, that there is no intentional limitation herein to the specilic form and precise details of construction shown and described, except as expressly defined by the appended claims, and that various modifications of the same may be resorted to Without departing from the spirit of the invention orV the benelits derivable therefrom. It is also to be understood that certain features of the invention herein disclosed may be employed in and with other combinations than those show and described. Y

What I claim as my invention and desire to secure by Letters Patent is l. In an egg beater or the like, the combination of a separable sectional frame includ-` ing normally interlocked sections, detachable beater members having their ends rotatively mounted in different sections of said frame, and means for rotating said beater members.

2. In an egg beater or the like, the combination of a separable sectional frame including an upper section and a lower section, means for normally interlocking said sections, beater members rotatively mounted at their upper ends within said upper section and similarly mounted at their lower ends within said lower section, and means for rotating said beater members.

3. In an egg beater or the like, the combination of a separable sectional frame including a rigid upper section and a resilient lower section adapted to be normally and yieldingly held within said rigid upper section, separately removable beater members rotatively mounted within said frame and means for rotating said beater members. Y
